Ka-band Reflectarray Unit-cell with 1-bit Digital Phase Resolution
A simple and low-profile reconfigurable unit-cell design for Ka band reconfigurable reflectarray antennas is presented in this paper. The unit-cell is based on a single substrate and a ground plane that allows a simple fabrication process. One p-i-n diode is used to control the reflection phase shift with a step of 180°. The optimization of the unit-cell structure is carried out with full wave simulation software. Radiation characteristics of a 10x10-element reflectarray is also validated in Ka-frequency band. Simulation results show that the unit cell exhibits a good 1-bit phase control within a wide bandwidth and the array achieves an excellent beam-steering capability with low loss and wide scan angle.
